Your Physical and Emotional Health: 1 Weeks Pregnant Symptoms

It is important to note that the symptoms you experience at this early stage are not actually pregnancy symptoms but symptoms that are reflective of your period and can last anywhere from three to seven days.

Pain in the lower back area and cramps – It is very common for women to feel pain concentrated in the lower back area in addition to cramping sensations. This is due to the contracting of your uterus in releasing the uterine lining along with the unfertilized egg from last month.

Bloating – There will be bloating! A woman’s period results in hormonal levels undergoing massive fluctuations that very often develop into bloating in the tummy and other areas. The bloating can occur in the days just prior to the beginning of a woman’s period as well as during her period.

Hormonal implications: Along with bloating, fluctuating hormonal levels often result in irritability, anger, and mood swings that can occur swiftly from minute to minute. Just as commonly resulting from hormonal fluctuations are migraine headaches during a woman’s period.

At the point your period has finished, your body will experience an increase in progesterone and the inner lining found within your uterus undergoes a transformational process in anticipation of the implantation of a fertilized egg, which will have made its way from the fallopian tube.

At this early stage, your baby is actually an ovum, which is a term for the egg. The ovum is so diminutive in size that it is barely perceptible to the unaided human eye. The tiny ovum will remain enshrouded; safely tucked away within your ovaries.
